Livestock manure processing of organic fertilizer first needs to be fermented and decomposed. The organic fertilizer after fermentation is used as the carrier and added with functional bacteria to produce bio organic fertilizer. Bio organic fertilizer is a kind of special organic fertilizer which contains fermenting microorganism which is beneficial to crop growth. It has the function of microbial fertilizer and organic fertilizer. It can obtain specific fertilizer benefits when applied in agricultural production.

There are many kinds of microbial fertilizer used in the production of bio organic fertilizer equipment, which can be divided into bacteria, actinomycetes and fungi according to the types of specific microorganisms in the finished products; Rhizobium, nitrogen fixing bacteria, phosphorus solubilizing bacteria and potassium releasing bacteria are classified according to their action mechanism; according to the number of microbial species added in organic fertilizer, it can be divided into single bio organic fertilizer and organic-inorganic compound organic fertilizer. There are two steps to process commercial organic fertilizer in the bio organic fertilizer production line: early fermentation and treatment part and deep processing granulation part. Bio organic fertilizer equipment needs fermentation compost windrow turner, crusher, mixer, fertilizer granulator, dryer, cooler, screening machine, coating machine, packaging machine, conveyor and other equipment. 

1. The recovered livestock and poultry manure directly enters the fermentation area. After one fermentation and two aging stacks, the odor of livestock and poultry manure is eliminated. At this stage, fermentation strains can be added to decompose the crude fiber, so that the particle size requirements after crushing meet the particle size requirements of the fertilizer granulator.
2. Pulverize the fermented materials that have completed the second aging and stacking process and enter the mixing mixer. Before mixing, according to the recipe, add N, P, K and some other trace elements to the mixing mixer to start mixing.
3. Transfer the mixed materials to the granulator, granules pass through the dryer and enter the cooling machine, the materials will be sieved after reaching normal temperature, and the particles that meet the requirements will enter the coating machine to wrap the coating film and start packaging, which does not meet the requirements The granules are crushed by the crusher and then returned to the granulator to continue granulation.
4. Automatic packaging of finished products.
